Q4) A SI engine four-stroke cycle v8, 0.005m3 displacement, mounted on a hydraulic dynamometer has an output of 53,6 kW at 4050 RPM. Water absorbs the energy output of the engine as it flows through the dynamometer at a rate of 0.113 m3 per minute. The dynamometer has an efficiency of 93% and the water enters at a temperature of 20°C.Calculate: (a) Exit temperature of the water. ['C] (b) Torque output of the engine at this condition. [N.m] (c) What is bmep at this condition? [kPa]
